think I solved my own problem and thought I'd pass this along to anyone else that has trailer light issues on the 2007 factory installed hitch.
the control box is located on the left side of the rear hatch near the tire jack. open up that lid and you'll see a small box suspended. the interesting thing is on the harnes itself, there is a small factory spliced fuse 7.5A that says "optional fusing". I guess my installer added this option.... sure enough the fuse was blown and after a quick change, works like a charm.
there is no fuse in my driver side front fuse box btw.
cheers to all!
